α-Indirect Control in Onion-like Networks

We propose a fast, accurate, and scalable algorithm to detect ultimate controlling entities in global corporate networks. α-ICON uses company-participant links to identify super-holders who exert control in networks with millions of nodes. By exploiting onion-like properties of such networks we iteratively peel off the hanging vertices until a dense core remains. This procedure allows for a dramatic speed-up, uncovers meaningful structures, and handles circular ownership by design. Read our paper with the applications. As a toy example, consider the […]

Graphic notes on Gilbert Strang’s “Linear Algebra for Everyone”

Graphic notes on Gilbert Strang’s “Linear Algebra for Everyone” The output file is “The-Art-of-Linear-Algebra.pdf“ Abstract I tried intuitive visualizations of important concepts introduced in “Linear Algebra for Everyone”. This is aimed at promoting understanding of vector/matrix calculations and algorithms from the perspectives of matrix factorizations. They include Column-Row (CR), Gaussian Elimination (LU), Gram-Schmidt Orthogonalization (QR), Eigenvalues and Diagonalization (Q Lambda Q^T), and Singular Value Decomposition (U Sigma V^T).

Building Docker images on GitLab CI: Docker-in-Docker and Podman

If you’re using GitLab CI to build your software, you might also want to use it to build Docker images of your application. This can be a little tricky, because by default GitLab CI runs jobs inside Docker containers. The standard technique for getting around this problem is using Docker-in-Docker, but you can also use a simpler technique by using Podman, the reimplemented version of Docker. Let’s see why and how. Option #1: Docker-in-Docker When you run the docker command-line […]
